- no check for negative offset.
many of these fix potential security problems in these drivers.

the d_mmap cdev routine should be changed to have a prototype like:

consoles for TC alphas. Based on code from Takuya Koumoto

struct scsipi_adapter; they were not used.
Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.

day.
- Convert to use bus_dma.
- Fix cleaning up unaligned start address.
- Correctly determine if the device supports Fast SCSI, and adjust the
minimum sync period accordingly.
- Compute minimum sync period correctly on the 25MHz devices.
- Use GPI2 to determine if we're a 25MHz or 40MHz device.
- Currectly determine SCSI ID and "fast mode enabled" for the built-in
TCDS on DEC 3000 models, using cached information from the PROM environment.
the namespace accordingly.
- Set FCLK in the CFG3 register if we have a > 25MHz clock.
- Indicate that we support Fast mode to the back-end if we're told we're
fast by the TCDS layer.
- Correctly compute the minimum sync period.
- Fix the autoconfiguration model; the TCDS children don't attach to
TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
TurboChannel driver (i.e. work on DECstations).
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
